On a typical desktop computer with a gigabit Ethernet connection, ZMap\nis capable of scanning the entire public IPv4 address space on a single port in \nunder 45 minutes. For example, sending a TCP SYN packet to every IPv4 address\non port 25 to find potential SMTP servers. With a \n10gigE connection and either [netmap](http:\u002F\u002Finfo.iet.unipi.it\u002F~luigi\u002Fnetmap\u002F) or \n[PF_RING](http:\u002F\u002Fwww.ntop.org\u002Fproducts\u002Fpacket-capture\u002Fpf_ring\u002F), ZMap can scan \nthe IPv4 address space in under 5 minutes.\n\nZMap operates on GNU\u002FLinux, Mac OS, and BSD. ZMap currently has fully implemented\nprobe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a\nlarge number of [UDP probes](https:\u002F\u002Fgithub.com\u002Fzmap\u002Fzmap\u002Fblob\u002Fmaster\u002Fexamples\u002Fudp-probes\u002FREADME).\nIf you are looking to do more involved scans (e.g., banner grab or TLS handshake), \ntake a look at [ZGrab 2](https:\u002F\u002Fgithub.com\u002Fzmap\u002Fzgrab2), ZMap's sister project \nthat performs stateful application-layer handshakes.\n\n> [!CAUTION]\n> Ethical Scanning\n> \n> Performing Internet-wide scans can have serious ethical and operational implications. While ZMap defaults to usually safe\n> settings, it is your responsibility to ensure that you're a good internet citizen. Rules of thumb are to scan at the\n> slowest speed necessary, scan slower if you're scanning a smaller target space, and provide a way for network operators\n> to opt-out. More information can be found [here](https:\u002F\u002Fgithub.com\u002Fzmap\u002Fzmap\u002Fwiki\u002FGetting-Started-Guide#%EF%B8%8F-warning-on-scanning-rate).\n\n> [!TIP]\n> We've collected some helpful tips and step-by-step walkthroughs for using ZMap in isolation or in a measurement pipeline with [ZGrab2](https:\u002F\u002Fgithub.com\u002Fzmap\u002Fzgrab2) in our [Getting Started section](https:\u002F\u002Fgithub.com\u002Fzmap\u002F#getting-started).\n\n\nUsing ZMap\n----------\n\nZMap is easy to use. A simple scan of the entire IPv4 space on TCP port 80 can be performed with the following command (requires root privileges):\n\n```sh\nsudo zmap -p 80\n```\n\n```\n$ sudo zmap -p 80\n...\n 0:00 0%; send: 5 1 p\u002Fs (185 p\u002Fs avg); recv: 0 0 p\u002Fs (0 p\u002Fs avg); drops: 0 p\u002Fs (0 p\u002Fs avg); hitrate: 0.00%\n52.8.107.196\n...\n 0:01 0%; send: 10327 10.3 Kp\u002Fs (10.1 Kp\u002Fs avg); recv: 118 118 p\u002Fs (115 p\u002Fs avg); drops: 0 p\u002Fs (0 p\u002Fs avg); hitrate: 1.14%\n````\n\nIf you haven't used ZMap before, we have a step-by-step [Getting Started Guide](https:\u002F\u002Fgithub.com\u002Fzmap\u002Fzmap\u002Fwiki\u002FGetting-Started-Guide) that details how to perform basic scans. Documentation about all of ZMap's options and more advanced functionality can be found in our [Wiki](https:\u002F\u002Fgithub.com\u002Fzmap\u002Fzmap\u002Fwiki).
